1. And yet marines are taught where to stab a knife to cause the most harm. Where do you think they learned that? At some point, some battle hardened army surgeon provided his medical opinion for a hand to hand combat training manual.
Pretending that this hasn't been going on since always is naive.
That oath you're talking about goes back to ancient times. Do you think that the doctors in the triage tents of the Roman legion wouldn't be happy to tell a Centurion how best to kill a man?
Your interpretation of the doctor's oath is not uncommon but it is not the classical interpretation of it. You are to do no harm to your patient in a doctor patient relationship so as to preserve the trust and respect of the medical profession.
The doctor's oath is a practical oath and not a religious one. It is also there so that doctors don't confuse experimentation with medicine. When most people sit down to get helped by a doctor they assume the doctor will first do no harm. However, if the you have an incurable disease and will try anything, many patients ask for the doctors to try ANYTHING.
This is where medical researchers come in and if they have approval, they can attempt unproven medical treatments on the theory that the fellow is going to die anyway so they might as well give something a try. And of course he must give consent for that.
Now lets compare this situation to the interrogation room. There is no doctor patient relationship between the psychologist and the terrorist. The terrorist doesn't need to trust the psychologist. There is no practical reason for the oath besides you misunderstanding of why the Oath exists and your dogmatic adherence to it.
The doctor is actually properly in the employ of the DoD in that situation... not the terrorist. And furthermore he is there as a researcher. And just as medical researchers will vivisect rats and cut apart human fetuses... well this fellow in the room is a test subject.
And it gets better because psychologists desperately need test subjects. They're not able to get them anywhere else. So, this actually offers them an avenue to conduct real science. You can't for example break the mind of a college student to study psychology. It is unethical. You can't do it to death row inmates because that is seen as unethical. You can't do it to extremely insane people that will never be able to lead normal lives again unless they are cured because that is considered unethical.
They can't actually preform science in most cases. But then here comes the CIA... and they say... do what you need to do, just get us the information.
You might think this all ghoulish and evil but think of it scientifically. How can you learn if you aren't allowed to take anything apart? And here we are... the CIA offering to let psychologists take a mind apart... psychologically strip them down and play with the core components. Evil? Debatable. We are talking about terrorists here. The information extracted from them could save lives or even tip the fate of nations from barbarism into modernity... possibly saving millions from short savage lives. And of course, learning something about the mind could mean new EFFECTIVE treatments for psychological disorders which could advance human knowledge.
So you see... the morality on the issue is quite cloudy.
2. As to breaking someone and losing my moral compass... I am not dehumanizing them actually. I just have a different concept of what being human means than you. If fully regard their humanity. And I would do it anyway.
You suggest I don't have empathy, but I do actually. I am extremely empathetic. Painfully so on occasion. But you are correct that I do not sympathize with the terrorist. I know he is a human. I know he is in pain and suffering from fear etc. I know it and I feel it. It gives me no pleasure. To the contrary, his suffering causes me to suffer as well. I do it anyway because I need the information.
Ironically it is you that are dehumanizing me. You are suggesting that because I do not hold to your ideology I am lacking human feeling. False. I feel as much as you if not more. It hurts me. But sometimes it has to be done.
3. As to how I know they're hardened terrorists, that is the premise of my argument. It was a given. A "assume these conditions" statement.
You wish me to consider non-hardened terrorists? Well, they should be easier to get to cooperate, shouldn't they? And that means needing to do less to get them either to accidentally tell us what we want to know or spook them so they just say what we want to know.
You don't need to hurt someone to make them talk. You fellows have such an amusingly medieval view of these things. Typically you can get what you want simply with a bit of theater. Simply putting on a grim face and creating an atmosphere that makes them feel like never going to get out is enough typically. The hardened ones would rather die of course. They thrive on the finality of death etc. So you need to break that mental state. There are many ways of doing that. Some of them are nasty and some of them will leave no marks.
4. As to interrogations and trials, we are speaking of a military setting... trials do not enter into it. During WW2 we interrogated hundreds of Nazi spies in the US. Typically they were held for perhaps a week or so until we felt we had everything of value out of them and then we shot them.
This conflation of military with civilian is silly. I do not hold a trial before I shoot a man on the battlefield. All I need to know is he is not an ally and he is not surrendering.
And before you bring up the PoW thing with the terrorists, they must wear uniforms to distinguish themselves from civilians to be considered enemy soldiers. Literally anything will work. A red bandana around an arm, a tattoo on the face... anything that separates them from civilians. And if they are caught wearing such a uniform then they are PoWs. If they are caught wearing civilian clothing AND weapons then they are neither civilians nor soldiers. And the Geneva convention is silent on that matter. I believe by international law I could probably eat them alive on international television without breaking the rules. So... explain again why I need to give anyone a trial?
The point of the war crimes trials was to negate the PoW status of Nazi war criminals. These are people that surrendered. And we killed them anyway because we determined that their actions were so bad prior to surrendering that we could not let them live.
As the people we hold in these cells are not PoWs unless you can cite some uniform they're wearing... are you instead saying that they're war criminals? I don't understand what legal precedent you're attempting to use here.
Can you cite something from history where anyone followed the rules you're talking about? Has the US ever made a practice holding a trial for every enemy they met on the battlefield? I'm not seeing the logic.
As to real interrogators... What do you do if the subject refuses to speak to you? Just says nothing at all. How do you start the conversation?
I'm sorry, but all carrot and no stick isn't optimal.
As to what is moral or not... that is your opinion. Explain to me why I should care more about your opinion than you do about mine? You clearly hold my position in contempt and feel no obligation to do things my way even though this is my opinion. So then why must I do things your way simply because that is your opinion?
Your position is illogical and possibly narcissistic or egotistical. You seem to think that something should matter because it matters to you? I am not motivated to respect that.
